SEAL ASSEMBLY FOR ELECTRICAL LOGGING PROBE Russian patent published in 2013 - IPC G01V3/18 E21B47/12 

FIELD: physics.

SUBSTANCE: disclosed is a seal assembly for an electrical logging probe, having a cylindrical housing, a plurality of dielectric inserts placed in the housing, a plurality of annular electrodes coaxially placed in the housing between the dielectric inserts and touching the end faces of the dielectric inserts with their end faces, an insulating means placed on the cylindrical housing for electrical insulation of the plurality of annular electrodes from the housing. According to the invention, each of the plurality of annular electrodes and dielectric inserts in contact with the annular electrodes have bevel end faces. The bevel end faces of the electrodes are interfaced with the bevel end faces of the dielectric inserts that are in contact with them. The seal assembly has a means of generating a compression force and fixing, which is in contact with the end face of the dielectric insert, placed distally with respect to said dielectric insert which is in contact with the cylindrical housing.

EFFECT: high containment of electric equipment of the probe from the external medium of the well and improved probing data.
